IterativeModelReconstruction

Reconstruction technology

IMR sets a new direction in CT image quality with industry-leading low-contrast resolution and virtually noise*-free images. Innovations in hardware and the reconstruction algorithm result in a reconstruction speed – less than three minutes for the majority of reference protocols – that allows model-based benefits to be achieved in even the most demanding applications.

IMR provides significant improvements in low contrast detectability, giving you confidence through enhanced visualization of fine detail and improved accuracy in detecting small, subtle structures. This outstanding improvement helps strengthen the position of CT as the backbone of radiology.

IMR Platinum is the first knowledge-based solution to overcome the motion sensitivity associated with traditional model-based solutions. This allows it to be used in highly advanced acquisitions, such as cardiac CTA.

* In clinical practice, the use of IMR may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. Low-contrast detectability and noise were assessed using Reference Body Protocol comparing IMR to FBP; measured on 0.8 mm slices, tested on the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using human observers.

** Image noise as defined by IEC standard 61223-3-5. Image noise was assessed using reference body protocol, on a phantom. Data on file.
